0.27 is the answer, hope it helps
O = number of oat cereal, w = number of wheat cereal, f = number of fruit cereal:
o + w + f = 4250
o = w + 715
f = 5w
The second equation tells us the value of o in terms of w, and the third equation tells us the value of f in terms of w, so we can plug in "w + 715" for o and "5w" for f in the first equation:
o + w + f = 4250
(w + 715) + w + (5w) = 4250
Then, add like terms and subtract and divide to isolate the w:
w + 715 + w + 5w = 4250
7w + 715 = 4250 Subtract 715 on both sides:
7w = 3535 Divide by 7 on each side:
w = 505
Now that we have w, we can plug it into the last equation to find f, the number of fruit cereal boxes:
f = 5w
f = 5(505)
f = 2525
Therefore, the factory packages 2525 fruit cereal boxes.
Answer:
Well we are adding by 10 for every 1 increase in x. So slope is 10 / 1 = 10. (1. a slope of 10) is an answer.
We want x = 1 to have y = -5 Slope form is y=mx+b. We know m = 10 bec slope is 10. We have the point (1,-5) on the graph so we solve for b by plugging:
-5 = 10(1) + b and this is b = -15. So graph has function y = 10x-15.
b is the y-intercept so (3. a y-intercept at (0,−15)) is an answer.
